Stator coil replacement for a Honda GL145

[Gareth123]

Anyone know what stator coil would be a suitable replacement? Mines poked.
I'm thinking a XL185 perhaps?

How hard is it to rewind them yourself? I figure if it won't cost me much for the materials I might give it a go.

It is easy mate. Though Motu will go on about being a miserly cheap cunt for doing so.......

I'll give it a go then.

Yeah it is. Take it to your local electric motor rewinder and tell them you want to rewind it yourself, and ask for some wire (likely to $6-8) and ask if they will dip it (in shellac) for you and bake it.

Tell them if the stator runs in engine oil, coz they might have to bake or shellac it differently. Some glues get sticky when reheated, and you don't want that shit through your engine oil.

Carefully take the wire turns off, counting them as you go, etc.

Because a machine would wind it tighter than I can with my bare hands, will I need to add more turns to make up for that?

NO. To cancel the increased area you would need to remove a turn.

Do not do this as the design of the regulator/rectifier will be designed with manufacturing tolerances in mind, and you don't know which direction (over or under inductance) is preferred; just replicate the original winding as best you can or buy a new one from a wrecker

This is correct, but if you think you might get away with it - add an extra turn or go up 0.1mm size wire, particularly if there looks like some spare room on the thing. It might work - it might not, but it won't cost you much to play with it, so have fun. I doubt you will toast a regulator doing it, but if you do - oh well...

n. I doubt you will toast a regulator doing it, but if you do - oh well...

clearly we have two very different views about motor vehicle maintenance and ownership.

maybe you should add that to your sig

and what do you mean by "it might work"? you're going for overvoltage as a compensator for overvoltage; why bother at all?

Yes we do. You consider it a safety thing, and I consider it an entertainment thing. My position is, if it's $4 worth of wire and glue, and it won't rip your leg off if it fucks up, then play with it. Different story if it's your front brakes.

There is little or no risk lowering the output impedance of the stator or raising its open-circuit voltage. All you will do is make the reg/rect run a little hotter.. or maybe you will fry it.. who cares? If you can eat the cost then do it.

Moving outside the square and not being limited by conventional thinking doesn't come at great risk or great price in this situation, so why not?

People will choose for themselves - I'm just a messenger.

Fixed that for you.

The most important thing is the number of turns of wire on the stator, the overall diameter of the windings will have less effect as long as they are in the magnetic field set up around the iron core. There is usually an insulator around the core inside the windings, have a good look to make sure this is still OK to stop the corners cutting through the insulation on the wire when you wind it on.

If you take careful note of how many turns of wire and the direction they are wound in you should be fine.

One turn from a fewe thousand turns will do 5/8th of fuck all.

I think there was 6000 turns on each of the two posts for my XR, I could find my work book that has it written down.......then I used the wrong wire so had to do it twice...

exactly

and what on earth adding a turn is meant to achieve even if it did have an effect is beyond me

On a 12V stator winding? I think my stator had about 30 turns per pole of 1.1mm dia wire (which completely filled it), which is what I was referring to.

The point I am making is, if you increase the turns AND the wire size, you will lower the source impedance of the stator and raise it's terminal voltage. This WILL load your reg/rect more heavily, and if you are unlucky it will toast it. The reason to do this, is increased output capacity.
